4. The Dollars Trilogy

Does it count as a trilogy when the three lead characters have different names, even if they’re all played by the same man, Clint Eastwood? Some would argue not, but they can make their own list. Sergio Leone created a genre, the spaghetti western, with this collection of hard-bitten, vocally-economical pieces. Leone’s camerawork and Ennio Morricone’s music are still copied routinely today.
